Brand Focus #23: Biotherm

Following her ground-breaking discovery of the skin-rejuvenating properties of thermal plankton, pioneering biologist Jeanine Marissal went about adding this extract to her skincare formulations.  
And so in 1952, French cosmetics company Biotherm was born. You’re probably wondering what this thermal plankton stuff is; it’s a water-dwelling microorganism, sourced from the thermal springs of the Pyrenees, that happens to be surprisingly similar in make-up to some of the key elements found in our own skin. Though now part of the prestigious L’Oréal Group’s portfolio, Biotherm (not to be confused with Bioderma) has stayed true to its water-faring roots. From deodorants to shaving foams, cellulite-busting body care to skin-soothing serums, Biotherm’s products are jam-packed with various blends of Pure Thermal Plankton, algae and cellular waters, all of which boast countless skin-beautifying benefits.
Biotherm is also committed to supporting projects, both locally and globally, which serve to protect our planet’s water sources. So much so, that 2012 saw the founding of their Water Lovers charity to which a portion of their proceeds from sales is donated. If you fancy dipping you toe into the waters of Biotherm’s plankton-packed products, your first port of call should be their Lait Solaire range of milky, citrus-scented sun creams. Offering broad spectrum (UVA and UVB) sun protection in a variety of SPFs, these absorb like a dream. Alternatively, try their age-correcting Blue Therapy Serum-in-Oil for night time. Containing more omega 3 fatty acids than you could shake a stick at, this product draws on special technology which allows the serum to transform into a nourishing oil upon contact with your skin.

Or, slather on some of their iconic Biomains Age-Delaying Hand and Nail Treatment. This is a lightweight, yet super-nourishing, hand cream whose SPF 4 wards off sun damage. It was one of the first ever products to come out of Biotherm’s lab and is still a firm favourite amongst customers.

Now, it’s over to you. Are you already a fan of Biotherm products’ plankton-y goodness? Are they a brand you’ve heard of before? If not, do you think you’ll now be checking them out?

    1. Too right, Biotherm has some cracking products out there. Thanks VERY much for commenting, Aerin.

  2. I have never tried Biotherm but this makes me want to try it.



    1. Yeah, you should do. My advice would be to get down to your nearest Boots, at the first glimpse of our British summer, and stockpile their Lait Solaire sun creams! Ooh, and thanks for reading.
